A news article that you read stated that 58% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 150 of the 300 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? Interpret the p-value in the context of the study. If the population proportion of voters who prefer the Democratic candidate is 58% and if another 300 voters are surveyed then there would be a 0.25% chance fewer than 50% of the 300 voters surveyed prefer the Democratic candidate. If the sample proportion of voters who prefer the Democratic candidate is 50% and if another 300 voters are surveyed then there would be a 0.25% chance of concluding that fewer than 58% of all voters surveyed prefer the Democratic candidate. There is a 58% chance of a Type I error. There is a 0.25% chance that fewer than 58% of all voters prefer the Democratic candidate. Interpret the level of significance in the context of the study. There is a 5% chance that the proportion of voters who prefer the Democratic candidate is smaller 58%. There is a 5% chance that the earth is flat and we never actually sent a man to the moon. If the proportion of voters who prefer the Democratic candidate is smaller 58% and if another 300 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 58%. If the population proportion of voters who prefer the Democratic candidate is 58% and if another 300 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is smaller 58%

Question

A news article that you read stated that 58% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 150 of the 300 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance?

Interpret the p-value in the context of the study.
- If the population proportion of voters who prefer the Democratic candidate is 58% and if another 300 voters are surveyed then there would be a 0.25% chance fewer than 50% of the 300 voters surveyed prefer the Democratic candidate.
- If the sample proportion of voters who prefer the Democratic candidate is 50% and if another 300 voters are surveyed then there would be a 0.25% chance of concluding that fewer than 58% of all voters surveyed prefer the Democratic candidate.
- There is a 58% chance of a Type I error.
- There is a 0.25% chance that fewer than 58% of all voters prefer the Democratic candidate.
Interpret the level of significance in the context of the study.
- There is a 5% chance that the proportion of voters who prefer the Democratic candidate is smaller 58%.
- There is a 5% chance that the earth is flat and we never actually sent a man to the moon.
- If the proportion of voters who prefer the Democratic candidate is smaller 58% and if another 300 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is equal to 58%.
- If the population proportion of voters who prefer the Democratic candidate is 58% and if another 300 voters are surveyed then there would be a 5% chance that we would end up falsely concluding that the proportion of voters who prefer the Democratic candidate is smaller 58%
